I guess the only thing to worry about would be checking the starting TBN of the d2 you use and making a judgement about what OCI to follow. I don't think that all d2 oils are super low SAPS like, say, M1 5W30 ESP, but you'd want to know exactly what you are dealing with. BITOGer edyvw shared a story about MB dealers in the US blindly using that M1 in all the vehicles they serviced and causing big problems for some of their customers with gas engines.
I believe that Pennzoil mentioned here that at least some people can find at WM is more like a 0.8% SAPS oil rather than 0.6% like M1 5W30 ESP, but I'd have to do some poking around to be sure of that.
OCI's will be relatively short. I'll run the dealer oil for 2k miles, then swap it out and run the XG and oil of choice until the OLM hits 20% (the level the dealer recommends to come in). That should be no more than 5k miles.
Alternatively, I run both oils out to approximately equivalent intervals (~3.5k miles each) and swap out the dealer installed PF64 with the XG the moment I get home from the free dealer oil change.
